TLDR: I want to update my Ipv6 only to DuckDns. ddns-updater gets the right ipv6 adress in the logs but don't send it to DuckDns. If the Update URL is without an adress, DuckDns try to detected the ipv4 adress. That's my problem.
If i understand it correctly the IPv6 should be place in the URL witch send to DuckDns, for example

https://www.duckdns.org/update?domains=xxxsubdomain1xxx&token=xxxTokenxxx&&ipv6=2001:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx:xxxx&verbose=true&verbose=true

  1. Is this urgent: Yes/No

  2. DNS provider(s) you use: DuckDns

  3. Program version:

  1. What are you using to run the container: docker-compose
  2. Extra information (optional)

Just set "provider_ip": false and that should do it 😉 Sorry for the long delay answering as well.

Although the program uses ip6 instead of ipv6 as the URL query parameter, so let me know if that doesn't work.

Hey @qdm12,
thanks for your response. 😊 I'm glad you are helping me.
Maybe i missunderstand you. In the LogFile you can see i set up two Subdomains.
Subdomain1 with "provider_ip": true and the other Subdomain2 with "provider_ip": false.
Both send only the ipv4 adress to DuckDNS.
I tried it anyway to set both Subdomains on "provider_ip": false but it still sends ipv4 addresses to DuckDns

What do you mean here? I can't wirte "ip_version": "ip6",in the config file ?

Ah I know why from the logs:

  • DEBUG record xxxsubdomain2xxx.duckdns.org is within ban period or cooldown period, skipping update so your subdomain2 was temporarily banned, and hence no update is done.
  • DEBUG GET https://www.duckdns.org/update?domains=xxxsubdomain1xxx&token=xxxTokenxxx&verbose=true doesn't have the ipv6 URL query parameter in there since this one uses provider_ip: true.

On the other hand, ERROR mismatching IP address received: 88.130.153.114 is a bit weird since the code should just blindly believe the provider to find our IP correctly instead of double-checking, when provider_ip is set.

Actually they mention it on duckdns.org, basically using provider_ip: true only works with ipv4, not ipv6. I updated the duckdns document in 1f9eb467ca to mention this.

Let's close this issue for now, but feel free to comment back if you got anything else going wrong. Thanks!
